The Mothers Behind the Musk Dynasty: From Author to AI Executive

The mothers of Elon Musk's children hail from diverse professional backgrounds, reflecting the various stages of his life and career. Understanding the relationships provides crucial context to the children's upbringing and public profiles. The four mothers are Justine Wilson, Grimes, Shivon Zilis, and Ashley St. Clair.

Justine Wilson: The First Wife and Mother of Six

Canadian author Justine Wilson was Musk’s first wife, whom he met in college. They were married from 2000 to 2008 and share six children together, though only five are living. Their first son, Nevada Alexander Musk, tragically passed away. The couple later conceived twins (Griffin and Vivian Jenna Wilson) and triplets (Kai, Saxon, and Damian Musk) through in vitro fertilization (IVF). The five surviving children with Wilson are now young adults, with the twins being approximately 21 and the triplets around 19 years old in 2025. This group represents the most private and traditionally raised of the Musk children, though Vivian’s decision to legally change her name and gender made headlines worldwide, signaling a significant distance from her famous father.

Grimes (Claire Boucher): The Avant-Garde Artist

Musician and artist Grimes, whose real name is Claire Boucher, has three children with Musk, all of whom possess names that are famously unconventional and rooted in technology and science fiction. Their first son, X Æ A-Xii, or 'X,' was born in 2020. Their daughter, Exa Dark Sideræl, nicknamed 'Y,' was born via surrogate in late 2021. The news of their third child, a son named Techno Mechanicus, or 'Tau,' was only revealed in 2023 through Musk's biography, though he was born in 2022. The children with Grimes are often at the center of public fascination due to their unique monikers, which Musk and Grimes have explained are inspired by everything from the speed of light to elven languages.

The Newest Additions: Shivon Zilis and Ashley St. Clair

The most recent chapter in the Musk family story involves two separate partners, both adding new members to the growing brood in rapid succession.

Shivon Zilis: The Neuralink Executive

Shivon Zilis, a director at Musk's neurotechnology company, Neuralink, has four children with the tech CEO. Their relationship was revealed in 2022 when court documents showed they had filed a petition to change the names of their twins, Strider and Azure, to include Musk's last name. The twins were born in November 2021, just weeks before Musk's second child with Grimes was born. Zilis and Musk have since welcomed two more children: a daughter named Arcadia, born in February 2023, and a son named Seldon Lycurgus, born in 2024.

This rapid expansion highlights Musk's stated belief that underpopulation is a major threat to civilization, a philosophy that appears to be guiding his personal decisions. Zilis has publicly shared updates about the children, often posting photos of them visiting SpaceX facilities, suggesting a close integration of their lives with Musk's professional world.

Ashley St. Clair: The Unrevealed Child

The latest confirmed addition to the family came in February 2025, when political commentator Ashley St. Clair announced that she and Musk had welcomed a child together in September 2024. This confirmation, five months after the birth, brought the total count of Musk’s children to 14. The name of the child remains unrevealed, maintaining a level of privacy that contrasts sharply with the public debut of names like X Æ A-Xii. This newest development ensures that the narrative of the 'Musk-eteers' continues to be a central topic of public discourse and curiosity.

The Impact of the Unconventional Musk Family

The focus on the 'Musk-eteers' goes beyond mere curiosity; it reflects a broader discussion about wealth, privacy, and parenting in the 21st century. The children's lives, from the young adults choosing to distance themselves to the toddlers with names that are viral sensations, are a mirror to the unconventional choices of their father.

The names themselves—ranging from the traditional (Griffin, Saxon) to the philosophical (Exa Dark Sideræl) and the technological (Techno Mechanicus)—often become global talking points, embedding the children's identities within the narrative of their father's tech-driven vision. As these 14 individuals grow up, their stories will continue to shape the public perception of the world's most talked-about entrepreneur, offering a rare glimpse into the complex family dynamics of one of the planet's most influential figures.
